Frequently asked questions
What is the coil voltage of Siemens 3RT1054-6NP38-0PA5?
Buyers must confirm the 200-277 V UC AC/DC coil range matches their control supply before purchase.
What does the -0PA5 suffix mean on a Siemens 3RT10 contactor?
The option code defines the PLC interface 24 V DC and busbar connections; misreading it leads to wrong part ordered.
Is the 3RT1054-6NP38-0PA5 suitable for solid-state relay interfacing?
The 2 NO + 2 NC auxiliary contacts are specified as solid-state-compatible, critical for low-current PLC I/O.
What replacement fits a Siemens 3RT1054-6NP38-0PA5?
Identifies direct cross-references and functionally equivalent S6 contactors when stock is constrained.
What is the difference between 3RT1054 and 3RT1055 contactors?
Differentiates the 55 kW (115 A) and 75 kW (150 A) ratings so buyers do not over- or under-size.
Where can I buy 3RT1054-6NP38-0PA5 with current stock and price?
Captures bottom-funnel buyers comparing authorized stockists and lead times for this MPN.
